Abstract: 316,257. PathÚ CinÚma, Anciens Etablissements PathÚ FrÞres. July 26, 1928, [Convention date]. Kinematograph apparatus.-Means for enabling a single image to be projected for a prolonged time comprises a coupling device for the shaft of the feed mechanism having a movable element controlled by a movable stop normally held away from it by means of a contact member engaging the edge of the film; the movable element rotates with the shaft, and moves towards and from it, and the stop is so placed that, when the feed mechanism is uncoupled, the feed claws are withdrawn from the gate. As shown, a driving shaft 1 carries a gear wheel 2 meshing with a pinion 3 loose on a shaft 4 carrying a shutter blade 15 and operating feed claws on a link 11. A disc 27 is secured to the shaft 4 and carries a spring- pressed pawl 24, Fig. 3, normally engaging a tooth 23 in a wheel 22 secured to the pinion 3. One arm 33 of a lever is urged by a spring 35 acting on its other arm 30 into a position such that it would engage the pawl 24 and uncouple it from the tooth 23, but is normally held by a projection 31 on a lever 21 pivoted at 26 and carrying a stud 20 pressed into engagement with the film edge by a spring 28. The film edge is notched, and, when the stud 20 falls into a notch, the lever 21 moves to the position shown in Fig. 5, and allows the arm 33 to engage the pawl and break the coupling. The end 29 of the lever 21 is raised by hand to restore the coupling. The stud 20 is moved away from the position of the film edge, when threading or rewinding is to be effected, by depressing the end 29 of the lever so that the surface 36 engages the lever arm 30. The coupling is then broken, and, since the pawl is placed on the disc 27 in such a position that the feed claws are withdrawn from the gate when the pawl is held, the gate is free for threading &c. Specification 316,255 is referred to.

Abstract: 314,022. Te Aroha Dairy Co., Ltd. June 14, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 22, 1929]. Preserving cream &c.-Cream and other liquids are pasteurized, deodorized and concentrated in a horizontal cylindrical steam-jacketed container having means at one end for admitting in an atomized or broken up condition the liquid to be treated and for causing it to form a peripheral revolving wall therein, a desired degree of vacuum being maintained within the container, and having means at the other end for discharging the liquid from the container. Means are also provided for maintaining a substantially constant volume of liquid in the container. In one form, the container 1 is surrounded by a jacket 2 to which steam is supplied through an inlet pipe 65 having a control valve 66 and a combined pressure and vacuum relief valve 67, a baffle 68 being fitted within the jacket to prevent the incoming steam impinging directly on the container. A drain pipe 69 and steam trap 70 are fitted at the bottom of the jacket 2. A vacuum is created in the container 1 by means of an ejector-condenser 42, which may be of the kind described in Specification 220,627, connected through conduit 36 to the container. The ejectorcondenser 42 has a water supply pipe 46 with a valve 47 and a pressure gauge 48, a vacuum gauge 49, a vacuum relief valve 50, a vacuum breaking cock 50<a> and a drain pipe 51 being also provided thereon. The liquid to be treated, which may be previously pasteurized or raised to a comparatively high temperature thus entering the apparatus hot, is next admitted to a float chamber 53 through a pipe 54 and a froth-eliminating valve 55 fitted to a removable cover 56, and causes a float 64 to rise opening a valve 62 through which the liquid passes to a pipe 57 leading to the container 1. A steam pipe 59, Fig. 3, having a valve 60 is coupled to a pipe 57 so that steam can be admitted to break up or atomize the liquid. Within the container are disposed blades 14, preferably three in number, attached to a boss 13 and carried by a. shaft 7 which can be rotated to revolve the blades 14 by a belt drive to pulleys 10, 11. A clearance of from inch upwards is provided between the blades 14 and the wall of the container, the clearance being varied according to the density and viscosity of the liquid. A revolving wall of liquid is thus formed within the container. The liquid is withdrawn through a pipe 23 by a centrifugal pump 15 which may be driven from shaft 7 by means of a chain 20, or independently. The pipe 23 has a water jacket 24 for cooling the liquid. The pump 15 has an outlet 21 provided with a check valve, through which the liquid passes from the apparatus. The container has a bye-pass pipe 27 connected through a valve 28 to the pipe 23 to enable the container 1 to be drained when the apparatus is to be stopped. The rear end 4 of the container is detachably secured to the container bv studs and hand-wheels 33, a rubber gasket 31 being interposed.

Filed: 1965-04-30
Abstract: 1,075,686. Embossing; printing-surfaces; coating with pre-formed sheets. HICKS & OTIS PRINTS Inc. April 30, 1965 [July 10, 1964], No. 18383/65. Headings B6C, B6G and B6J] Sheet material 10 having voids therein (e.g. foamed polyurethane of polyester or polyether type, batting made from nylon fibre or polyester fibre &c.) is drawn by feed rollers 15, 16 between rollers 12, 13, the roller 12 being provided with a plurality of holes 20 arranged in a desired pattern. Water, which may have dye material incorporated therein, is supplied to the roller 12 from a trough formed by a doctor blade 21, and is transferred from the holes to the sheet on contact therewith, forming heatresistant printed areas. The sheet then passes over a plate 14 and under a flame 18 from fuel in a perforated pipe 17, and where not protected by the heat-resistant material, the material of the sheet is fused so that the voids are filled and the material collapses, depressing the surface in the unprinted areas. A fabric sheet 24 can then be laminated to the embossed sheet, adhering only to the fused portions, or the sheet may have a fabric backing. If the water is thickened with starch or methyl cellulose, the sheet can be formed with areas depressed to different depths by varying the depths of the holes 20. Printing-surfaces.-An intaglio roller 12 is formed with holes 20 of varying depth arranged in a required design, the holes taking up the printing-material and transferring it to the sheet to be printed. Coating with pre-formed sheets.-A sheet of foamed polyurethane or fibrous batting is stretched before having applied thereto a fabric sheet, so that when it returns to normal size, the fabric exhibits small decorative folds.
